Subject [jira] [Created] (DRILL-2854) KVGEN function document needs to be corrected
Date Thu, 23 Apr 2015 17:41:38 GMT
Khurram Faraaz created DRILL-2854:

             Summary: KVGEN function document needs to be corrected
                 Key: DRILL-2854
                 URL: https://issues.apache.org/jira/browse/DRILL-2854
             Project: Apache Drill
          Issue Type: Bug
          Components: Documentation
    Affects Versions: 0.9.0
            Reporter: Khurram Faraaz
            Assignee: Bridget Bevens

The sample JSON data snippet here (http://drill.apache.org/docs/kvgen/) needs to be corrected
and additionally the SQL query to produce the output listed in that section, can be added
to that section.

Here is the correct representation of the data in the JSON data file. Currently the text on
documentation page is missing the "rec1" identifier, and the opening and closing braces for
"rec1" are also missing.

[root@centos-01 bin]# hadoop fs -cat /tmp/simplemaps.json
{"rec1":{"a": "valA", "b": "valB"}}
{"rec1":{"c": "valC", "d": "valD"}}

Query that produces the desired output, like the one mentioned in the documentation section
for KVGEN function.

0: jdbc:drill:> select kvgen(rec1) from `simplemaps.json`;
|   EXPR$0   |
| [{"key":"a","value":"valA"},{"key":"b","value":"valB"}] |
| [{"key":"c","value":"valC"},{"key":"d","value":"valD"}] |
